What we have learnt
- Living organisms exhibit a hierarchical structural organization from cells to organ systems.
- Animal tissues are categorized into epithelial, connective, muscular, and nervous tissues, each serving distinct functions.
- Plant tissues include meristematic and permanent tissues, with further classifications into simple and complex tissues.
Key Concepts
- -- Levels of Organisation
- The hierarchical arrangement of biological structures from cells to organ systems.
- -- Animal Tissues
- Tissues in animals categorized into four types: epithelial, connective, muscular, and nervous, each with specialized functions.
- -- Plant Tissues
- Plant tissues categorized into meristematic and permanent tissues, which can be simple or complex based on cell types.
